Causes of automatic flameout of excavators.
Poor engine oil supply leads to automatic flameout of excavator.
It shows that the engine speed is unstable or slowly decreasing before shutdown, but there is no obvious black smoke in the exhaust pipe. In this case, check whether the fuel in the fuel tank is exhausted, whether the oil supply of the oil transfer pump is normal, whether the oil inlet of the sedimentation cup is blocked by sundries, and whether the diesel filter is too dirty. If the diesel filter is too dirty, remove it, clean it and reinstall it, and remove the air in the oil circuit. The digging machine is automatically closed.
The sudden interruption of engine oil supply or sudden increase of load leads to the automatic flameout of the excavator.
Before the excavator flamed out, there was no deceleration process, but it suddenly flamed out. In this case, first check whether the engine parts suddenly loosen or fall off. For the engine whose high-pressure oil pump oil supply rod is controlled by the flameout solenoid valve, check whether the flameout solenoid valve is powered off. The reason why the excavator shuts down by itself.
